[Struts 2 + EJB 3] Display an image
Hi,
I have an entity bean which has a BLOB attribute. That BLOB attribute
maps to a BLOB column in a table in an Oracle database.
@Entity
public class Boo implements Serializable {
...
@Lob
@Basic(fetch=FetchType.LAZY)
private byte[] image;
public byte[] getImage() {
return image;
}
public void setImage(byte[] image) {
this.image = image;
}
...
}
I also have an Action class where i query that entity bean and put the
result into the session :
public class MyAction extends ActionSupport implements SessionAware {
...
Public String someMethod() throws Exception {
Boo boo = blaRemote.findById(l);
session.put("boo ", boo );
...
}
Finally in my JSP i display the various values of the attributes of that
Entity bean, including that image attribute :
<s:property value="#session.boo.attributeN" /> <br />
<img src="<s:property value="#session.boo.image" />" /> <br />
Of course I can display the value of all attributes except the image.
How do you display an image with Struts 2 ? Is there a specific tag for
it ?
Thanks for helping.

Hi,
Thanks for helping.
Well, I of course needed to call the action in my <img> tag.
It works.
Thanks again.

Hi Fernandes,
i think that it is impossible what You are trying to achieve.
You cannot pur image to img tag inside html.
Img tag will result in just another http request, and this another request must be serviced by your server.
So the code will look like this:
<img src="/showMyimage.action?id=123" />
And showMyImage action will simply return image as a result.
Also read very carrefully above e-mail from Saeed!
Best greetings,
Paweł Wielgus.

Are you putting the file name in session string or the binary file?
